A cell taken from the embryo that can differentiate into any type of specialised cell.

A cell found in specific regions of the body that can differentiate into a limited number of related specialised cells.

A differentiated cell that is adapted to carry out a particular function.

When a patient’s immune system attacks non-self cells (e.g. transplants).

An ethical issue relates to whether an action and its consequences are right or wrong.

Using stem cells in medicine: potential benefits, risks and ethical issues

Combined science

Specialised cells, unspecialised cells and differentiation

Stem cells in animals

Meristem cells in plants

Pupils will learn about the roles of hormones in human reproduction, including control of the menstrual cycle, and other uses of hormones such as in in contraception.

Pupils learned about growth through cell division, mitosis as part of the cell cycle, cancer as the result of changes in cells that lead to uncontrolled growth and division, and the formation of gametes by meiosis.

This unit explores the function of stem cells and the importance of cell differentiation. It discusses the benefits and risks of stem cell use in medicine, evaluates applications of science, and considers the personal, social, economic, and environmental implications of scientific decisions.

embryonic stem cells can only differentiate into a few types of cells

Why do some people object to the harvesting of embryos as a source of embryonic stem cells?

the access to embryonic stem cells is limited

viruses can spread between stem cells in culture

Which of the following are risks of using stem cells?

Which type of stem cells are likely to cause an immune rejection?

True or false? Egg cells contain a nucleus.

Many mitochondria to provide energy for contraction.

Biconcave shape to provide a large surface area for diffusion.

Contains chloroplasts for photosynthesis.

Match the specialised cell to its adaptations that help it carry out its role.

True or false? Embryonic stem cells can only differentiate into a limited and related number of cells.
